DETERMINATION OF ACTIVE SWEET COMPONENTS OF COMMON ARTIFICIAL SWEETENERS THAT ARE USED AS REPLACEMENT FOR SUGAR

ABSTRACTThis research investigated how the sweetness of sugar substitute compares to the sweetness of sugar. In this research different percentage solution of sugar, artificial sweetener and natural sweetener (10%, 1%, 0.1% and 0.01%) were prepared. Ten volunteers were gathered for the sensory evaluation in this case tasting of the solution, the volunteer‟s taste threshold of data was gotten. The artificial sweetener was found out to be the sweetest among the substances experimented and at the percentage of 0.1% and 0.01% saccharin an artificial sweetener was able to mimic the taste of sugar. Research prove that artificial sweetener are non-nutritive they have virtually no calories in contrast to sugar which contains 4 calories at each gram, a teaspoon of sugar is about 4 grams, for weight lose artificial sweetener may be an attractive option to sugar. Artificial sweetener may also be a good alternative for diabetic patient, unlike sugar; artificial sweeteners generally don‟t raise blood sugar levels because they are not carbohydrates.

Some sugar substitutes are natural and some are synthetic. Those that are not natural are in general, called artificial sweeteners. Artificial sweeteners and other sugar substitutes are found in a variety of food and beverages marketed as sugar free or diet including soft drinks, chewing gum, jellies, baked goods, candy, fruit juice and ice-cream and yoghurt. [Whitney 2011] People may not all like the same kind of baked treats but one thing we all agree on is that baked treats should be sweets usually, sugar is used to lend sweetness to foods but would cake taste just as good if the baker used a sugar substitutes instead of sugar? Many people prefer not to use sugar often due to health reasons and instead depend on sugar substitutes to sweeten their foods. But are sugar substitutes the same as sugar? What exactly are the differences between sugar and sugar substitutes?Sugar also known as sucrose comes from plants like sugar cane and sugar beets and is a carbohydrate. Sugar adds bulk to cakes, cookies and all kinds of treats; sugar also causes browning and caramelizing in foods when it isheated as when cookies turn golden brown in the oven sugar is a natural substance, something that our bodies can use for energy.Sugar substitutes come in three categories; artificial sweeteners, sugar alcohols and natural sweeteners. Artificialsweeteners are attractive because they add almost no calories to foods and are sometimes a part of weight loss programs. Also they donot increase blood sugar levels which mean that diabetics can use them. Many artificial sweeteners like sucralose were discovered by accident in the laboratory. In 1976, a scientist in England was studying different compounds made from sugar. The scientist asked a student to test the compounds but instead the student tested them. Another category of sugar substitutes is sugar alcohols. Sugar alcohols are not alcoholic beverages they do not contain ethanol which is found in alcoholic beverages. Sugar alcohols like sugar have calories and energy but not asmuch as sugar. Sugar alcohols like artificial sweeteners do not contribute to tooth decay and affect blood sugar levels slowly so diabetics can use them. Although sugar alcohols like xylitol, sorbitol and erythritol are manufactured products the sources are often natural.
